VENTIL-ATOR.

Specification of Letters Patent.

Patented Mar. la, 1916.

Application led June 24, 1913. Serial No. 775,532.

To all whom t may concern.'

- Be it known that I, GEORGE F. MEYER, a citizen of the Unitedl States, residing at Smithton, in the county of Petti's and State of Missouri, have invented certain new4 and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to ventilators, which are well adapted to be used in connection with windows or the like, while not necessarily restricted to such use, and has particu.-

' lar reference to aventilator of this type which is adjustable whereby the desired amount of air may be admitted to a room or the like.

An important object of this invention is to provide a ventilator of the above mentioned character, which will aHord a proper free passage of air into a groom or' lthe like without creating a draft.

A further object of this invention is to provide a ventilator of the above mentioned character, having screening means to prevent the passage of insects or the like into the room, such means being arranged within the apparatus whereby the same is `thorapparatus.

oughly protected.

A further object of this invention is to' provide a ventilator of the above mentioned character, which is simple in construction, compact in the arrangements of its parts, easy to operate, strong and durable.

Othertobjects and advantages of the invention will be apparent during the course of the following description.

In-the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, Figure 1 is an outer side view of the apparatus, Fig. 2 is a plan view of the same, Fig. 3 is a central longitudinal sectional view through the same, Fig. l is a perspective view of the movable casing or housing included in .the apparatus, and, Fig. 5l s a similar view of a co-actlng stationary casing included in the In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 6 designates a body portion or sash-rail, which is preferably formed of wood, although other material may be employed. Connected with `one end of the body portion or sash-rail 6 is formed of sheet metal,

a cap 7, preferably by screws 8 or the like.

and attached thereto a longitudinal plate 10, having its free end bent in' the form of a curved handle 11, as

shown. The longitudinal plate 10 is provided with an elongated slot 12, receiving a clamping screw 13, or the like.

The body portion or sash-rail 6 is provided with a large longitudinal opening 14, for receiving the inner portion of a stationary casing 1o, which is preferably formed of sheet metal. The outer portion of this stationary casing extends beyond the body portion or sash-rail and is closed by a perforated side plate 16, as shown. The ends of the casing l5 are provided with openings 17. The casing 15 is attached to the body portion or sash-rail 6 by means of screws 18 or in the stationary casing 15 whereby it is protected from rain and the like, while the sameA v serves to prevent insects from entering the house. The open frame 2l incldes ends strips 211, having longitudinal slots 25, for receiving guide pins or screws 26, as shown, which positively limits the outward movement of the casing 19. The casing 19 is moved by a knob or handle 27, attached to the plate 20, as shown.

In the use, the apparatus may be installed within awindow, so -that the sash will engage the sash-rail 6, when lowered. The apparatus may be permanently attached to a sash, either the upper or lower, a door, or

Vmay be built into theside of the room. It

is obvious that by moving the casing 19 the air passing into the room may be regulated, such air passing laterally through openings 22, whereby a draft is avoided.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in theshape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope lof the sub-- distance, said caslng having air circulating openlngs 1n its ends, lts. top closed, lts'inner' 51de open, and its outer side covered by a perforated protectingv plate; an inner frame mounted to reciprocate transversely Within the casingV and having its sides and ends provided With-air circulating openings; an

imperforate plate secured to the inner side of the frame to move it for regulating the amount of air circulating through the openings in the frame and carrying a handle; a section of lWire mesh secured to the outer open side of the frame tained within the outer casing to tec'ted thereby.; and means to limitthe invWard movementy of the frame with relation to the outer. casing. l

In testimony whereof I aiiX my signature 1n presence of two Witnesses.
